Application nl, u, 1m, sumNo. 15ans My .invention relates broadly to desk sets and moreparticularly to an improved construction of inkwell and arrangement ofdip pen for use in coaction therewith.

One of the objects of my invention is to provide a construction ofinkwell of the hydrostatic .pressure type which may be readily molded in`one piece from synthetic materials. f

Another object of my invention is to provide an inkwell of thehydrostatic type having an v4integrally molded base and ink reservoirsupporting portion and including an integrally molded dip pen supportcapable of beingl manuactured inexpensively on a quantity productionasis.

Still another object of my invention is to provide a construction ofinkwell and integrally connected dip pen support by which the pen may bemounted in a convenient position at all times to allow withdrawal of thepen from a position substantially sealing the passage extending totheink reservoir for a convenient writing operation.

A further object oi' my invention is to provide mounting means for a dippen in a hydrostatic linkwell in which a substantially frictionless bindis provided between a portion of the dip pen holder and the pen guideportion of the inkwell whereby a relativelyrtight seal ma be readilybroken upon grasping and lifting the pen holder from the inkwell.'

A still further object of my invention is to provide an arrangement formounting a dip pen in the pen receiving. receptacle of a hydrostaticinkwell in which coacting parts are provided in the pen receivingreceptacle and on the dip pen so that the thrust of the pen uponinsertion into the ink receiving receptacle is stopped at the mouth ofthe bore and a substantialseal established adjacent the mouth of thebore, the bore being arranged both as a guide and' a securing means incoaction with the dip pen supplied for use with the hydrostatic inkwell.

Another object of my invention is to provide a construction of pen guidefor a hydrostatic inkwell 'wherein the bore of the pen guide is shapedto coact with a soft resilient rubber disc carried by the dip pen forinsuring the sealing of the pen receiving receptacle against dust andother foreign matter tending-to interfere with the of the inkwellpermitting the level of the ink in 'comme (0mm-ss) between the penholder and the pen receiving receptacle.

A further object of my invention is to provide a construction ofhydrostatic inkwell molded from synthetic v'material and including a penre- I, ceiving receptacle and a compression escapement channel directlyformed in the wall of the pen receiving receptacle.

A still further object -of-my invention is to provide a construction ofmolded hydrostatic inkwell which may be formed either wholly orpartially from transparent material allowing the ink level in theinkreservoir to be readily dbserved from the exterior of the inkwell.

Other and further objects of my invention reside in the arrangement. ofseal between the dip pen holder and the penv receiving receptacle as setforth more fully in the specification hereinafter following by referenceto the accompanying drawings in which:

The hydrostatic inkwell of my invention is molded from syntheticmaterials in'one piece 50 which includes the integrally connectedhousing, base and intermediate pen receiving receptacle. The penreceiving receptacle has the axis thereor disposed on an acute anglewith respect to the horizontal base. The lower end of the pen re- 55portion 3 of base-2.

ceiving receptacle connects through a port with the ink reservoir. Thefunnel shaped entranceway to the pen receiving receptacle is shaped to vcoact with the end of the dip pen holder and inof. The pen employed incoaction with the ink- 'well of my invention is mounted eccentricallywith respect to the pen holder allowing a substantially frictionlessseal to be eiected between the end of the pen holder and the penreceiving receptacle. 'I'he eccentric construction of the pen holderpermits a relativelytight seal to be established between the pen holderand the pen receiving receptacle. The same can be readily brokenhowever, without danger of sticking. The pen receiving receptacle andport at the lower extremity thereof is so shaped in coaction with thefunnel shaped upper extremity of the pen receiving receptacle that uponinsertion of the pen the thrust is stopped in the mouth of the bore ofthe pen receiving receptacle, thus protecting the pen point. Two zonesoi abutment are provided between the shaped end of the pen holder andthe pen receiving receptacle, that is, a substantially angular abutmentbetween the end of the pen holder andthe interior cylindrical wall of-`the pen receiving receptacle and the angular abutment between the funnelshaped extremity of the pen receiving receptacle and a shaped portion ofthe dip pen. .For further increasing the seal, I interpose a softresilient rubber disc between a portion of the pen holder and the inkreceiving receptacle.

I may construct the housing of the inkwell wholly `from synthetictransparent material or removable panels may be provided in the walls ofthe housing, the panels having suillcient transparency to allow thelevel oi' the ink to be' continuously observed or the panels beingformed from suitably colored material for lending ornamental appearanceto the inkwell.

Referring to the drawings in detail, reference character I designatesthe moldedl housing -of the hydrostatic inkwell which is formedintegrally with the horizontally extending hollow base 2. Thehorizontally extending hollow base 2 has a at portion which I haveindicated 'at 3 which bears substantially flange-like relation to thehousing I. The housing I includes not only the upwardly projectingportion I which extends above the at portion 3 of base 2 but also adownwardly projecting portion 4 integrally united with the housing I andbase 2. The downwardly projecting portion 4 is smaller in the lateralcross sectional area than is the upwardly projecting portion. Thedownwardly projecting portion 4 unites with the upwardly projectingportion I through an intermediate shoulder 9 disposed in a planesubstantially above the plane of the iiat The shoulder 5 provides aperipheral support for the inverted ink bottle which'I have showngenerally at 6. The ink bottle 6 has a relatively narrow neck 'I whichextends downwardly into the ink receiving reservoir 8 formed in thedownwardly projecting portion 4 of the inkwell. The ink bottle isintroduced into the open top of the inkwellby'removal oi' the top 9. Thetop 9 engages with the upper peripheral edge of housing I through thecoacting peripheral portion Ia on housing I and peripheral portion 9a oncover 9.

Intermediate the base 2 and housing I, I providea pen receivingreceptacle shown generally at l0. 'Ihe pen receiving receptacle isdisposed on an axis which extends at an acute angle with respect to thehorizontal base. The pen receiving receptacle has a rounded funnelshaped upwardly extending wall I 5 of the downwardly projecting portion4. The lower .extremity of the frusto-conical section I4 is connectedthrough port I6 with the ink receiving reservoir 8. The parts of the penreceiving receptacle III are proportioned in a very special manner forthe purpose of supporting the dip pen in a manner which will be pointedout hereinafter in more detail.

The dip pen is shown as including a pen holder II, a portion of which isconstituted by a hollow barrel portion having a compression releaseaperture I8 therein. The pen holder terminates in a chamfered shoulderI9 which coacts with the funnel shaped upper end portion shown at II.The pen'holder supports the cylindrical member 20, terminated in arounded shoulder 2I which coacts with the interior oi the bore of thepen receiving receptacle IIJ.V The member 20 provides a carrier for theeccentrically mounted pen point 22 which is maintained in position incoaction with the ink feed member 23. .The eccentric mounting of the penpoint may be readily observed by supporting the pen holder between theforengers with the pen point bearing against one forenger and ,the vendof the pen holder against the iorenger of the other hand and thentwisting the pen holder, whereupon the eccentricity imparted to the penby reason of the particular mounting thereof in member 20 will bereadily apparent. This eccentric mounting is important as it allows theentry of the pen point into the pen receiving receptacle by the coactionthus so shaped as to insure a substantially dust tight seal for theinkwell. As the pen holder is -thrust into the pen geceiving receptacle,the nib of theipen at 24 is deeeted by the frusto-conical wall portionI4 of the pen receiving receptacle to guide the pen point into asubstantially central position tending to move the shoulders I 9 and 2linto frictionless binding engagement with the funnel shaped extremity II and the internal bore I0 of the pen receiving receptacle. The thrustof the pen is stopped at the mouth of thebore I0. An abutment isestablished between chamfered shoulder I9 and funnel -II and betweenshoulder 2l and the interior bore of pe'n receiving receptacle I 0.There is a tendency for a suction seal to be established when the pen isthrust vinto the pen receiving receptacle. This suction is brokenhowever, if the lingers grasp the^pen holder and impart a slight angularmovement thereto, rocking the pen holder in the pen receiving receptacleandbreaking the vacuum seal at one side of the pen receiving receptacle.

In order to further seal the pen receiving receptacle into which the penholder is inserted, I

provide a soft resilient rubber disc 26 which is apertured at 26' to lltaround member 20 below chamfered shoulder I9. When the pen`slides intothe funnel shaped entrance II of the pen receiving receptacle, therubber disc of its very nature conforms to the shape of the opening,sealing it against dust. Moreover, the soft'rubber disc 28 shields thefingers against contact with ink deposits on the lower section of thepen holder. .The soft resilient rubber characteristics of the disc aresuch that both the sealing function and the shielding function arereadily performed by the disc.

I provide a compression escapement channel 21 intermediate thedownwardly projecting portion l and the upwardly projecting portion Iof" the housing. The compression escapement channel is disposed betweenthe upper portion of the downwardly projecting wall I i and the frontwall of the housing I. The compression esca-pement channel 21 extendsbetween the upper portion of pen receiving receptacle .III and theinterior of the housing I above the level of the ink in the inkreceiving reservoir 8, insuring equalization 'of pressures in thehydrostatic inkwell and pen receiving receptacle.

I may provide a capillary for insuring the continuousfeeding of 'inkfrom the ink bottle i to the ink receiving reservoir 8. I have indicatedthe capillary at 2 8 having a branch portion 29 for insuring thecontinuous feeding of the' ink. In

Fig. 9 I have shown more clearly the construction of capillary whereinthe upper portion thereof is substantially tubular and the lower portionis split into two semi-cylindrical portions, one of whichextends intothe ink receiving reservoir 8 and the other of which extends upwardlyinto the ink bottle 6.

In order to permit observation of the s upply of ink in the ink bottle 6I may provide transparent panel sections 30 or 3l in the front or rearwalls of the housing I. The housing I is slotted and provided withgrooves 30a or 3Ia into which the panelsll' or 3| having coactingtongues 30h or SIb may slide. The panels, or 3i, instead of beingtransparent, may be of colored material for imparting ornamentation tothe inkwell.

I may construct the inkwell wholly from transparent lmaterial so thatthe supply of .ink in the ink bottle 6 is at 'all times readilyobservable andl also the inkwell provides a high ornamental appearanceas a xture for the desk. The arrangement of the transparent inkwell isshown in Fig. 6 in which I have numbered all of the parts heretoforeexplained with (corresponding characters with a prime niark addedthereto. 'Il'he same integral construction of the several partsincluding the base, the housing, the ink receiving reservoir, and thepen receiving receptacle is employed in the form illustrated in Fig. 6as is the casein l the gures as heretofore explained.
